So you need a Zelda-like Battle System? Well, the one commonly used on this forum is Blizzard Action Battle system, Blizz ABS for short. It is also known as bABS and BABS, btw. You can find it in the RMXP Script Database board on this forum. It's a 'stickied' topic, so you can find it somewhere on the top. Another battle system you might like to try is XAS ABS. It has some other functions, like a hook shot. But the enemies of Blizz ABS are so smart that they can kill you while they're sleeping (in the case you take this serious, no, they can't sleep, but they're REALLY smart, because of Blizzard's awesome scripting powers. ALL HAIL BLIZZARD!).
For the sprites, the spriteset you're giving isn't a character sprite (probably). It is an animation sprite. XAS has an in-built full spriteset of Arshes, but I don't recommend you to use that, since Arshes is used in a lot of games already because of this. You can find other fully animated Blizz ABS sprites on this forum. Go to the Recourse Database board on this forum for that.
Off topic: I don't mean anything with this, but I suggest you to read/watch some tutorials on mapping. A good tutorial I learned from is by WillowSidHe. It's on youtube. Link:
Good luck with your game!
